“Unfortunately I cannot provide any more details as this is a sensitive ongoing investigation,” Rice said.

The US Secret Service also is assisting in the investigation at the request of the Moore Police Department, said Ken Valentine, special agent in charge of the agency’s Oklahoma City office.

“Where we have expertise, be it in cyber or electronics, that we can assist them with, then we do,” Valentine said.

No federal charges have been filed against Shortey.

State prosecutors charged Shortey last week with engaging in child prostitution, transporting a minor for prostitution and engaging in prostitution within 1,000 feet of a church. He was released on a USD 100,000 bond.

The state Senate last week voted on a resolution to strip Shortey of most of his power, including his ability to serve on Senate committees and author bills. The Senate also took away his office, executive assistant and parking space.

Several Republican leaders have called for Shortey to resign, including Governor Mary Fallin.

But senators have not voted to expel Shortey, which would take a two-thirds vote, so he will continue to draw his USD 38,400 annual salary. Shortey also will likely be eligible to collect his state retirement, even if he is convicted of the charges.

Joseph Fox, executive director of the Oklahoma Public Employees Retirement System, said Shortey became vested in the state’s retirement system last year after serving six years in the Oklahoma Senate.

Oklahoma law allows for the forfeiture of retirement benefits only if the felony conviction is for bribery, corruption, forgery, perjury or a felony related to campaign finance or the duties of office.

If Shortey contributed the maximum amount to his retirement, he would be eligible to collect USD 9,216 annually after he turns 60, according to state retirement calculations.
